Screw rpm tsis yog qhov tso zis tawm ntawm nws tus kheej. Kev hloov ceev hloov pauv cov khoom thauj khoom, lub sijhawm melting, shear, lub zog tsim thiab lub sijhawm nyob, yog li qhov txiaj ntsig zoo yuav tsum raug txiav txim nrog qhov kub thiab txias, lub cev muaj zog load, siab thiab cov khoom zoo.
Teb ceev
Kev ua kom ceev ceev feem ntau ua rau cov cab ntws thiab tus nqi ntawm cov khoom nkag mus rau hauv cov txheej txheem, tab sis kev sib raug zoo tsis txwv tsis pub los yog zoo kawg nkaus linear. Ntau rpm tseem tuaj yeem ntxiv cov cua sov, txo lub sijhawm nyob thiab nthuav tawm cov khoom noj tsis muaj zog lossis melting seem.
Hloov ib qho kev hloov pauv ntawm ib lub sijhawm, tos kom muaj kev ruaj ntseg, tom qab ntawd sib piv cov zis, yaj qhov kub thiab txias profile, siab, lub cev muaj zog load thiab cov khoom zoo. Nres thaum ib qho ntawm lawv ncav cuag nws qhov kev pom zoo txwv, txawm tias tus tsav tuaj yeem tig nrawm dua.
Nyeem cov extruder ua ib qho kev sib txuas
Cov khoom nkag mus rau hauv cov khoom loj, dhau los ua lub txaj compacted, melts, mixes thiab tawm los ntawm txoj kev txwv tsis pub khiav. Lub cev muaj zog muab cov khoom siv hluav taws xob thaum lub thoob tso cua sov thiab cov cua txias sib hloov pauv nrog cov txheej txheem. Cov ntsia hlau thiab tuag sib koom ua haujlwm siab.
Ib txoj kev tshawb fawb txog kev lag luam hauv xyoo 2016 tau sim peb cov polymers, peb cov ntsia hlau geometry, tsib speeds thiab peb qhov kub thiab txias, rau 135 lub sijhawm ua haujlwm. Cov kws sau ntawv ntsuas lub zog xav tau thiab yaj qhov kub thiab txias sib txawv ua ke. Lawv cov txiaj ntsig tau hloov pauv nrog cov khoom siv, ntsia hlau thiab cov xwm txheej, uas yog vim li cas ib txoj cai thoob ntiaj teb rpm-rau-tso tawm yog tsis ntseeg.
Peb lub Hoobkas saib:qhov chaw ua haujlwm zoo tshaj plaws tsis yog qhov siab tshaj rpm lub inverter txais. Nws yog qhov ruaj khov ntau tshaj plaws uas nyob hauv qhov pom zoo lub cev muaj zog, gearbox, siab, kub thiab cov khoom lag luam tsis zoo. Yog tias ib qho kev txwv tuaj txog thaum ntxov, txheeb xyuas qhov kev tsis sib haum xeeb ua ntej xaj kom tsav nrawm dua lossis lub hau ntswj tshiab.
Dab tsi hloov thaum ntsia hlau ceev nce
Siab dua rpm txav cov ntsia hlau nto nrawm dua piv rau lub thoob. Nyob rau hauv ib tug ruaj khov ntau yam, qhov no yuav ua rau kom cov khoom thauj thiab yaj conveying. Nws kuj hloov pauv tus nqi shear, txhua yam khoom siv hluav taws xob, lub sij hawm muaj rau melting thiab tus naj npawb ntawm cov ntsia hlau revolutions ib yam khoom siv.
Cov kev taw qhia ntawm melt-kub hloov tsis yog universal. Ib txoj kev tshawb fawb HDPE xyoo 2014 tau siv peb cov viscosities, peb cov ntsia hlau geometry thiab ob peb qhov ceev thiab ntsuas kub. Nws pom tias cov ntsia hlau hom, resin viscosity, teem kub thiab ceev tag nrho cov cuam tshuam lub zog siv thiab yaj sib xws.
Ib leeg-flighted screws pom qhov tseem ceeb ceev qhov twg melting zoo deteriorated, thaum kuaj barrier ntsia hlau tuav zoo dua kub uniformity.
Barrel teem kub tsis yog lub melt kub
Tus maub los qhia txog lub hom phiaj ntawm lub tshuab cua sov thiab feem ntau yog qhov kub thiab txias ze ntawm phab ntsa ntawm lub thoob. Polymer nyob rau hauv cov channel kuj tau txais txhua yam zog los ntawm deformation thiab kev sib txhuam. Cov cua txias tuaj yeem tshem tawm ib feem ntawm qhov cua sov, tab sis qhov kawg yaj tuaj yeem nyob kub, txias dua lossis tsawg dua li ib qho kev nyeem ntawv qhia.
Ntsuas qhov kub thiab txias ntawm qhov chaw uas tau hais tseg thiab hais txog cov txheej txheem sensor. Xyoo 2006 Polymer Engineering & Science txoj kev tshawb fawb tau siv cov txheej txheem thermocouple hla cov yaj ntws. Nws pom cov cheeb tsam uas tsis muaj qhov kub thiab txias ntawm qhov siab tshaj plaws nrog ib leeg-flighted screws, thaum lub sij hawm sim barrier ntsia hlau nrog Maddock tov khoom tiav zoo melting thiab qis variation.
Tsis txhob txo qis txhua qhov chaw tso cua sov vim tias qhov ntsuas tau yaj yog kub.Yog tias cov ntsia hlau tsim cov cua sov feem ntau, qhov txo qis tuaj yeem tawm hauv lub txaj txias dua thaum shear tseem siab. Tshuaj xyuas qhov twg melting tshwm sim, tso zis tso cua sov, cua txias teb thiab lub cev muaj zog load ua ntej hloov tag nrho profile.
Vim li cas cov zis nres tom qab rpm hauv txoj kab ncaj nraim
Thaum qis qis, lub tshuab nqus tsev zoo tuaj yeem pom qhov ze-linear kev sib raug zoo ntawm rpm thiab huab hwm coj ntws. Qhov kev sib raug zoo ntawd tsis muaj zog thaum cov pellets tsis ua rau cov channel sib npaug, qhov kev hloov pauv ntau, lub caj pas pub, melting poob qab, los yog downstream tsis kam hloov lub siab-flow tshuav.
Ib txoj kev tshawb fawb 2022 University of Stuttgart piv tus du, helically grooved thiab axially grooved noj zones ntawm lub siab ceev ceev. Nws pom qhov pib dhau qhov uas dhau los ua qhov tsis yog linear, thiab cov duab pellet thiab qhov loj me cuam tshuam qhov pib. Qhov no txhawb nqa txoj cai ntawm lub Hoobkas: sau cov khoom noj tiag tiag nrog rau lub npe polymer.
Yuav ua li cas nyeem Nanhaiya qhov kev tshaj tawm ceev thiab tso zis ntau yam
Nanhaiya tshaj tawm cov lus hauv qab no hauv tsev neeg ntawm ob qho tib siib leeg ntsia hlau qebthiab PE / PP nplooj ntawv siab ceev. Nws muaj txiaj ntsig zoo rau kev txheeb xyuas lub tuam txhab cov khoom lag luam tau teev tseg. Nws tsis yog ib qho kev ua haujlwm lav rau cov khoom tsis raug cai thiab tuag.

Cov lus nug uas nquag nug
Puas ua kom ceev ceev ib txwm nce extruder tso zis?
Tsis yog. Cov zis tuaj yeem nce nrog cov ntsia hlau nrawm hauv lub qhov rais ua haujlwm ruaj khov, tab sis pub muaj peev xwm, pellet daim ntawv, ntsia hlau geometry, melting muaj peev xwm, tuag tsis kam, lub cev muaj zog load thiab hnav tuaj yeem txwv qhov tshwm sim. Thaum muaj kev kub ceev, cov zis tshwj xeeb tuaj yeem poob lossis yaj tuaj yeem ua tsis zoo.
Puas yog lub thoob teeb kub tib yam li qhov kub thiab txias?
Tsis yog. Barrel setpoints tswj cov cua sov cheeb tsam, thaum lub polymer kuj tau txais txhua yam zog los ntawm cov ntsia hlau tig thiab shear. Ntsuas cov yaj ntawm qhov chaw uas tau teev tseg nrog lub ntsuas qhov tsim nyog thiab sau cov txheej txheem es tsis txhob kho tus maub los teeb tsa raws li qhov ntsuas kub tiag tiag.
Vim li cas melt kub nce thaum ntsia hlau ceev nce?
Cov ntsia hlau siab dua tuaj yeem ua rau nce tus nqi shear thiab cov khoom siv hluav taws xob. Qhov kub hloov pauv ntau npaum li cas nyob ntawm cov viscosity resin, ntsia hlau geometry, sau, chim profile thiab downstream kuj. Qee cov ntsia hlau thiab cov khoom sib xyaw ua ke yuav ua rau pom qhov tsis zoo lossis tsis tiav melting dhau qhov ceev ceev.
Vim li cas cov zis tuaj yeem nres nce txawm tias thaum rpm nce?
Cov khoom noj yuav tsum tsis txhob ntim cov khoom sib npaug, pellet plam tuaj yeem hloov pauv, qhov ntom ntom tuaj yeem sib txawv, lub peev xwm yaj tuaj yeem ncav cuag, lossis tuag thiab lim kuj tuaj yeem txwv lub kaw lus. Ib lub kaus mom hnav thiab lub thoob tuaj yeem ua rau kom cov pa tawm thiab txo cov twj siv tau zoo.
Cov neeg ua haujlwm yuav tsum sau dab tsi tom qab hloov cov ntsia hlau ceev?
Sau qhov tseeb ntsia hlau ceev, pub tus nqi, tso zis, yaj kub thiab variation, yaj siab thiab variation, lub cev muaj zog load, cheeb tsam kub, txias teb, cov khoom zoo thiab lub sij hawm tso cai mus cuag ib tug tshiab khov kho mob.
Cov ntaub ntawv dab tsi kuv yuav tsum xa Nanhaiya rau qhov tso zis siab ib zaug ntsia hlau saib?
Xa cov qib resin thiab daim ntawv, additives thiab fillers, yuav tsum tau tso zis, tam sim no rpm, lub cev muaj zog thiab gearbox cov ntaub ntawv, chim profile, yaj kub thiab siab tiam sis, tuag thiab lim cov ntsiab lus, ntsia hlau thiab chim drawings, hnav kev ntsuas thiab cov khoom tsis xws luag los yog ntau lawm txwv koj yuav tsum tau daws.
Cov ntawv sau cia: Nanhaiya cov khoom tshwj xeeb thiab cov lus thov raug txheeb xyuas raws li cov ntaub ntawv tshaj tawm hauv tuam txhab. Kev tshawb fawb ywj pheej txhawb nqa cov txheej txheem kev sib raug zoo, tsis yog kev lees paub rau txhua tus qauv Nanhaiya. Cov kev txwv zaum kawg thiab kev lees txais yuav tsum muaj cov khoom siv, tshuab, kev pom zoo kos duab thiab cov phiaj xwm kev sim.
